US Margin Debt Hits $1.5T Record as Retail Borrowing Surges
Total US margin debt reached an all-time high of approximately $1.5 trillion in June 2026, driven by a surge in retail borrowing. Robinhood’s margin book hit a record $21.6 billion in Q2, up 127% year-over-year. While this leverage amplifies gains, it also increases the risk of forced selling during market downturns.
